To all whom it may concern:

Be it known that I, OLIVER M. POLLOGK, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Tiltable Headlights, of which the following is a specification, reference being had therein to the accompany-ing drawin p a This invention re ates to tiltable head lights for automobiles and the like.

It has been proposed heretofore to tilt'the head lights of an automobile to cause the light to be directed onto the road immediately in front of the automobile and to thus remove the glare of the same from the eyes of persons approaching the machine with-' out depriving the driver of the light on the roadway. The object of the present invention is to provide a tiltable head light'having a very strong, rigid supporting structure which will hold the head light firmly in position and which will permit the same to be easily tilted M A further object'of the invention is to provide a tiltable headlight which will be returned to its norr'rial' position by means of a spring without jar or'shock such as would tend to injure the filament of the lamp.

Other objects of the invention will appear as the device is'described' in detailL. lln the accompanying drawings Figure 1 is a perspective view of the forward portion of an automobile showing the invention applied thereto; Fig. 2'is a side elevation, partly in section, of one of the lamps and its supporting structure together with the actuating device therefor; and Fig. 3 is a sectional view taken vertically through the forward portion of the housing.

In these drawings have illustrated one embodiment of my invention and having shown the same as comprising an elongated housing 1, open at its upper end and provided at its lower end with means for attaching the same to a supporting structure,

such as a tapered pin 2 adaptedto. extend through a supporting bracke't'and'having its lower end threaded to receive a nut 3. Pivotally mounted in the housing near the lower end thereot is an arm t which pro 'eratin cable; but obviouslly 0i jects beyond the open end thereof and supports the head light 5. The head light may be secured to the arm in any suitable manner but I prefer to cast therattaching bracket ointegralwith the arm4. The housing fits snugly against the sides of the'arm 4 to hold the same against lateral vibration and is of suilicient width to permit of the necessary pivotal movement of the arm to tilt the head light. To avoid the necessit of making the housing of. undue Width prefer that the upper edge thereof should be inclined upwardly and rearwardly, as shown at 7,

and inasmuch as the upper edge of the front wall of the housing constitutes a stop which limits the forward movement of the arm it will be apparent that the arm will have a relatively large movement.

The supportingarm 4 may be actuated in any suitable manner and in the present i11 stance it is retained normally in its upright} or retracted, position by means of a spring 8. A cam, or eccentric disk, 9 is mounted on a shaft 10 journalecl in brackets 11 secured to the side walls of the housing and projects through a slot 12 in the rear wall of the housing to engage and actuate the arm. The shaft has secured thereto a rock arm 13 to which is connected a cable 14 which extends dow'nwardly. about a guide pulley 15 thence rearwardly to a point near the driver s seat where it is connected with a suitable actuating device. In. the present construction the actuating device is in the form of a rod 16 slidably mounted invsuitable guides, 17, secured'to the steering column and is provided with a notch '18 adapted to engage the upper guide 17 to retain the head light in its tilted position. The guide pulley 15,1nay be mountedin any suitable manner, but I prefer to"; mount the same upon an extension of theppin 19 upon which the arm 4' is mounted. ithe two head lights of the automobile are independently mounted and are connected one to the other only by means of theshaft 10 which operates the cams for the two head lights. In the present construction 1 have provided a single 0 if it should e desire a double cable cou be used so that power could be applied to the shaft at both MW I ends thereof. I havehe're shown the housing as provided at its lower end'with an opening 20 to permit the escape of dust or dirt which may thereof. I I H To absorb the shock due to the return of the arm-"by this spring 8 and thus prevent iniuryto the lamp filament, or other parts of the mechanism, I have provided a cushioning device which is preferably in the' form of a dash pot 21 having mounted therein a plunger 22 which is connectedwith the arm 4. The dash pot may be mounted in any suitable manner butas here shown it is cast integral with the rear half of the housing, and the plunger 22 is connected with the rod by means of a link, or connecting rod, 23, which is pivotally connected at its respective ends to the plunger and the arm 4.

It will be apparent that when the head lights are in their normal positions a pull on the operating rod 16 will rotate the shaft 10 about its axis and cause the cams to engage the arms of the two head lights, thus rocking these arms about their axes and tilting the head lights. As soon as the actuating rod is released the springs 8 will return the arms 4, and the head lights, to their normal positions, this movement being retarded by the cushioning device which. absorbs the shock incident to this movement. The device is of a very strong, rigidconstruction which Wlll stand up well under the vibratlon due to the travel of the machine, and the device is very easily operated and requires but a minimum of attention on the part'of the driver.

While I have shown and described one embodiment of my invention 1 wish it to be understood that l do not desire to be limitedto the details thereof as various-modiliieations may occur to aperson skilled in t e art.

Having now fully described my invention,

I tached to a vehicle, an arm pivotally mounted on said supporting member, a head light secured to said arm at apoint remote from its axis, a shaft mounted on said supporting member, and a cam mounted on said shaft and acting on saidarm to rock the same about its axis and. tiltisaid head light.
